Specification of Letters Patent.

Patented Nov. 1, 1910.

Application filed April 15, 1910. Serial No. 555.648.

T 0 all whom it may concern.

lie it known that I. l laxns'r I GAnoN, a citizen of the United States. residing in the city of Newark. in the county of Essex and State of New Jersey. have invented certain new and useful Improvements in \Vater-Meters, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make. construct, and use. the same, reference being had to the accompanying drawings. and to letters oi reference marked thereon. forming a part of this specification.

This invention relates to that type or class of water meters generally known as the current or inferential, and has for its particular ob]ect. to so construct and mount a smgle propeller wheel 1n the outlet chamber of the water meter, that the water in the lower chamber exerts an upward pressure against the propeller wheel, but has no comnnmication with the outlet chamber, while the water in the upper chamber passes through the propeller wheel into the outlet chamber.

The invention consists in a water meter, which comprises a main casing having upper and lower receiving chambers, and an outlet chamber. a cylinder mounted in said outlet chamber, which is provided with uJper and lower bearings sup orting a spind e, a propeller wheel 1nounte on the spindle and provided with means which co-act with means on the cylinder, the arrangement being such that the water in the lower casing does not pass through the wheel or outlet chamber, but. exerts an upward thrustagainst the under side of the wheel, while the 'ater from the upper chamber is delivercd to the wheel and discharged into the outlet chamber.

In the accompanying drawings forming a part of this specification, Figure 1 is a vertical longitudinal center section of a meter showing an embodiment of my invention. Fig. 2 is a top plan view, the cover being removed. Fig. 3 is a side elevation of the spider. Fi 4 is a side elevation of the propeller wheel. Fi 5 is a side elevation of the cylinder; and Fig 6 is a plan view of the same.

Similar letters of reference refer to like parts throughout the specification and drawings.

The main or external meter casing a has the usual inlet 1) and outlet 0. The inflowing steam from the inlet 1) is caused to divide and pass it and down to the receiving chambers I) and If of the main or external easing (I. as indicated by the arrows. The outlet c is connected to the annular outlet chamber (1, in which is mounted the cylinder and the propeller wheel f. The propeller wheel f is fixed to the spindle g, which by suitable connections at its upper end, drives a register gear train in the usual manner, the regis er being inclosed in the housing It secured to the 11d '11. A skeleton frame or spider j mounted upon the cylinder (1 is secured together with the cylinder to the annular outlet chamber (1 by suitable connections, such as screws k. and the said spider y and cylinder e contain-the bearings l for the propeller spindle g.

The propeller wheel 1 is the indicating device employed to indicate the velocity and hence the volume, and consists essentially of a helix or screw Whose axis coincides with the flowing stream and which is caused to rotate by the impact or friction of the moving water, as is common in meters of the type generally known as current or inferential meters, and is provided with helical wings or blades m formed on its periphery through which the water from the top passes, causin the wheel and its attached spindle g and t e register train to revolve. The propeller wheel f is provided with a downwardly extending internal bearing m for the spindle g, and also with a downwardly extending tubular extension n co-acting with a tubular extension '22- formed on the cylinder e. The cylinder 0 on its under side is provided with a series of openings n and a bearing Z for the spindle g. The weight of the propeller wheel is supported by a suitable bearing n, the interior of which has screw-threaded engagement with the exterior of the bearing Z. The periphery of the cylinder 0 is provided with ports a through which the water after passing through the helical wings or blades m of the propeller wheel f passes to the outlet chamber and through the outlet 0. The cylinder 6 is mounted, preferably, vertically in a bearing 0, 0 formed in the upper and lower partitions p, p, which with the circular end wall 9 form the outlet chamber (Z. The cylinder e at its upper end is provided with an annular flange e which rests on the upper partition p, and is secured against accidental displacement upwardly by the skilled in the art.

plest operative efficiency.

screws 70, which at the same time secure the I an upward thrust against'th'e under side of the propeller wheel, whileflthe water fromthe upper chamber is deliveredthrough the helical blades of the propeller wheel to the outlet chamber and through the outlet 0. The structure illustrated revents' the steam entering the lower 0 amber from communicating with the intermediate outlet chamber at or the outlet 0.

The present invention provides a very efficient and exceedingly simple water'meter, the same being constructed of a minimum number of parts and reduced to'the sim- I am aware that changes may be made in the several arrangements of the various parts, as well as in the details of construction thereof, without departin scope of my present invention, ence,'I do not wish to be limited to the exact arrangements and combinations of the parts as here- 'in shown and described, as obvious modifications, will suggest themselves to those I claim:

1. In a water meter, the combination with a main casin havin .upper and lower receiving cham ers an an intermediate outlet chamber, a propeller wheel mounted in said intermediate chamber, so arranged that the water in the lower chamber exerts an upward pressure against the'propeller wheel, but has no communication with the outlet chamber, while the water in the upper chamber passes through the propeller wheel into the outlet chamber.

2.- In a water meter, the combination with a main'casing having upper and lower receiving chambers and an intermediate outlet chamber, a cylinder mounted in said inter-' mediate outlet chamber provided with openings' communicating with said outlet chamber, a. propeller wheel mounted in said cylinder, so arranged thatthe water in the lower a main casin chamber exerts anupward pressure against the propeller wheel but has no communication with the, outlet chamber, while the water in the upper chamber passes through the propeller wheel into the outlet chamber.

.3. In a water meter, the combination with havin upper and lower receiving cham ers an an intermediate out" let chamber, a cylinder mounted in said infrom the i 'means which co-act with means on said cyl inder, so arranged that the water in the lower chamber exerts an n ward pressure against the propeller wheel ut has no communication with the outlet chamber, while the water in the upper chamber. passes through the propeller wheel into the outlet chamber.

4. In a water meter, the combination with a main casin havin ceiving cham ers an an intermediate outlet chamber, a cylinder; mounted in said -intermediate outlet chamber, a propeller wheel mounted in said cylinder provided with centrally depending means so arranged that the water in the lower chamber fills up said depending means and exerts an upward-pressure against the under side of the wheel, but

has no communication with the outletchamber, while the water in the upper chamber passes through outlet chamber.

'5'. In a water meter, the combination with a main casing having upper and lower receiving chambers and an 'outletchamber, a

upper and lower rethe propeller wheel into the cylinder mounted in said outlet. chamber and 5 provided. with up er and lower bearings, a spindle sup orted 1n the bearings, and. a propeller whee provided with a tubular extension mounted on said spindle, the cylinder being provided with a tubular extension coacting with the tubular extension of the propeller wheel, the arrangement being'such that the water inthe lower casing exerts an upward thrust against the under side of the propeller wheel, while the water from v the upper chamber is delivered to the wheel and discharged into the outlet chamber;

6. In a water meter, the combination with 1 a main casin having upper and lower re-v ceiving cham ers and an intermediate outlet chamber, said intermediate outlet cham.- ber being open at the top and closed at the bottom, a cylinder mounted in said outlet chamber provided with a bearin a propeller wheel rovided with a tubu ar extension, said tu ular extension engagin with the bearing on the cylinder so as to orm a receiving chamber, the arrangement being ERNEST E.
